Implementation of parallel algorithms and simulation of different interconnection networks need an effective tool, that is, graph embedding. This paper focuses on improving a lower bound obtained in Rajan et al. (Comput J 58:3271–3278, 2015) for dilation of an embedding onto circulant networks. In addition, this paper provides algorithms to compute dilation of embedding circulant network into certain trees, for instance, m-rooted complete binary tree, m-rooted sibling tree, and r-dimensional hypertree, proving that the improved bound obtained is sharp.
